Coaxial arrester
For protection of coaxial data transmission equipments
New type lightning protector for coaxial cable consisting of coaxial connector and high performance gas-filled surge voltage arrester. By screw of connection ring protector can be connected easily with coaxial cable and equipment. Though small type, the protector has high impulse current withstanding. As the transmission performance, frequency band is wide, VSWR and insertion loss are also excellent.
